Brazil and Portugal's fisheries ministers are urging the global community to embrace blue foods as a vital climate strategy at COP30. They highlight that blue foods, which include fish, shellfish, and seaweed, have a lower environmental impact compared to traditional animal-source foods. By increasing the consumption of these foods, global CO₂ emissions could potentially decrease by over a gigaton annually. The ministers stress the need for countries to incorporate blue foods into their climate action plans to enhance food security and nutrition. As COP30 unfolds, blue foods will be a focal point in discussions, with initiatives aimed at reducing greenhouse gas emissions in fisheries and aquaculture. Brazil's innovative practices in aquaculture and Portugal's commitment to sustainable ocean management serve as examples for other nations. The ministers call for collaborative efforts to harness the benefits of blue foods for climate mitigation and adaptation.
